Water Ring Pelletizing Line  

Challenge: Frequent Screen Clogging & Downtime 

of Pelletizing Line

In the plastic recycling and pelletizing process, screen clogging, 

frequent screen changes, and maintenance-related downtime 

have long been major factors affecting production efficiency.

This is particularly true for contaminated recycled materials 

such as films and woven bags; traditional screen-changing 

methods not only increase consumable costs but also 

compromise the equipment's continuous operating capability.

How Does Our Pelletizing Line Solve This Challenge?

To address this industry challenge, we have launched a water ring 

pelletizing line featuring a screenless screen changer and a water ring 

pelletizing system. This combination enables continuous, stable production, 

delivering higher efficiency, consistent pellet quality, and lower 

overall operating costs for our customers.

⭐ Screenless Filtration: Lowering Operating Costs

Traditional Screen Changer: Require periodic screen changes, 

which consumes time and increases procurement costs.

Screenless Filtration: Eliminates the need for traditional screens 

by utilizing a specialized filtration structure for continuous processing. 

This effectively reduces downtime and maintenance frequency, 

ensuring long-term, stable operation of the entire production line.

✔ For plastic recycling enterprises requiring long-term continuous 

production, this translates to higher equipment utilization 

and lower production costs.

⭐ Water-Ring Pelletizing for Uniform Granules

Equipped with a high-efficiency water-ring pelletizing system, 

the molten plastic is pelletized immediately after extrusion through 

the die head, resulting in uniform size, smooth surfaces, and 

consistent appearance.

Water-ring cooling rapidly dissipates heat, effectively preventing 

the granules from sticking together.

✔ Stable pelletizing performance not only elevates product quality 

but also enhances the market competitiveness of the recycled granules.

⭐ High-Performance Extrusion System for Superior Plasticization

Utilizing an optimized, high-efficiency screw and barrel design, 

the system ensures thorough plasticization and uniform melting, 

resulting in highly stable output.

Paired with a precision temperature control system, processing 

parameters can be flexibly adjusted to maintain consistent output 

and excellent product quality across various operating conditions.

For recycled plastics containing moisture or volatile substances, 

an optional vacuum degassing system is available to effectively 

remove gases and moisture, thereby enhancing granule density 

and final product quality.

⭐ Automated Control for Simplified Operation

The entire line features an intelligent PLC control system that 

enables centralized management of all process stages and 

supports fully automated operation.

The intuitive interface displays real-time operating status, 

reducing the complexity of manual operation while facilitating 

maintenance and troubleshooting to boost production 

management efficiency.
